This PE-based high concentration red masterbatch is produced with carefully selected high-grade composite red pigments and mature precision compounding technology, solving common pain points of traditional red colorants such as dim color, uneven coloring and poor weather resistance. It presents a vivid, pure and uniform red tone on finished plastic products with no color deviation or fading spots, greatly improving the appearance grade of plastic finished goods. With a durable weather-resistant formula, the masterbatch enables end products to maintain stable bright red color for a long time, resisting color fading and discoloration caused by ultraviolet rays and natural climate changes.
Boasting a high heat resistance of up to 260°C, this red masterbatch adapts to the high-temperature processing environment of PE blown film, injection molding and pipe extrusion processes. It will not decompose, discolor or produce harmful substances during thermoforming, ensuring clean and stable molding quality. Its upgraded molecular dispersion technology realizes uniform pigment distribution inside the carrier, completely avoiding pigment precipitation, agglomeration and floating issues in mass production. Adopting regular free-flowing pellet design, it supports automatic industrial batching and uniform mixing, effectively boosting production efficiency and reducing manual operation costs.
In terms of industrial applicability, this eco-friendly red masterbatch features stable physical and chemical properties and will not damage the original mechanical performance of PE substrates, including toughness, tensile strength and impact resistance. Benefiting from high pigment concentration and super tinting capacity, only 1%–5% addition ratio is required to achieve ideal saturated coloring effects, bringing significant cost advantages for large-scale production. It covers multiple application fields, including food-safe plastic packaging, daily consumer plastic goods, PE blown film products, injection-molded plastic parts and extrusion molding products, fully meeting the diversified coloring demands of modern plastic processing industries.

For the best coloring uniformity and finished product quality, fully premix the PE red masterbatch with pure PE resin evenly before formal production processing. This product is slightly hygroscopic, so it must be kept away from humid working environments. Unused masterbatch should be tightly sealed and stored in a cool, dry and ventilated place to prevent moisture absorption and dust contamination, ensuring stable dispersion and coloring performance for next use.
